Duplisea Duplessis and Sirois Genealogy by Mark S Duplisea 

Home Database Surname History Sirois History Duplessis History About the Site

This website aims to present the history and genealogy of the SIROIS-DUPLESSIS family. It focuses on the  descendants of Francois Sirois dit Duplessis, an immigrant from France, who settled in Rivière Ouelle, in the Kamouraska region of Québec sometime around the year 1700. It also contains other ancestral lines for some of Francois' descendants.

Francois married twice and fathered at least thirteen children. In the late 1700's his descendants began to spread out from Kamouraska, primarily moving up and down the southern shore of the St Lawrence River and southeast into the St John River valley along the New Brunswick - Maine border.

Today most of his descendants to whom the family name has been passed on are known as Sirois, a few are known as Searway, and some King -- a partial translation of Sirois.  One branch of the family dropped the Sirois name and carry today as their surname Duplessis or a variation of it, like Duplisea
